Going out of various misunderstandings of preventing computer radiation

For a long time, the wave of electromagnetic radiation hyped by the manufacturers of radiation protection products has endangered the survival of human beings, which has lured many producers of daily necessities to follow suit and continue to sell protective products known as "the world's leading technology" to consumers, such as: Anti-computer radiation glasses, gloves, face masks, tops, pants, even pregnant women's special suits, etc., strangers, natural cosmetics businesses will not miss such a good opportunity, a variety of "anti-computer radiation cosmetics" is put on a high-tech corolla Whitewash debut. Let us proceed from the principles of basic scientific knowledge and explore the true face of these "flowers in the fog".

We truly understand the essence of computer electromagnetic radiation, without being distorted by exaggerated propaganda. It punctured the so-called "anti-computer radiation cosmetics" lie and found a symptomatic beauty rehabilitation path for computer skin problems.

What is the "magnetic radiation" generated by the computer?

Basic physics tells every middle school student: When an electric current flows in a conductor, a magnetic field must be generated in its external space, and the magnetic field lines with a certain energy flow from one magnetic pole to another magnetic pole. We humans live in such a natural And a large artificial magnetic field. If the magnetic field is too strong, it will cause "magnetic pollution" to the human body.

There have been reports in the literature: In 1998, the World Health Organization listed five major effects of electromagnetic radiation on the human body:

1. Electromagnetic radiation is the main cause of cardiovascular disease, diabetes and cancer mutation;

2. Electromagnetic radiation causes harm to human reproductive system, nervous system and immune system;

3. Electromagnetic radiation is the inducing factor of pregnancy, abortion, infertility and teratology;

4. Electromagnetic radiation directly affects children's development and bone development, resulting in decreased vision, retinal detachment, and decreased hematopoietic function of the liver;

5. Electromagnetic radiation can reduce physiological functions, female endocrine disorders, and menstrual disorders. This is the main basis for those manufacturers shouting "radiation hazard". They confuse "magnetic pollution" with the "magnetic effect" of normal survival. What we should discern is that these problems that harm the human body originate from "pollution" caused by excessive electromagnetic.

Judging from the data provided by many environmental protection materials: when the computer is running, the electromagnetic waves emitted by the main body of the chassis and the monitor will cause pollution to the surrounding environment, which is not good for health.

The radiation amounts of each component of the computer are:

Keyboard 1000v / m;
Mouse 450v, 4n;
Screen 218v, fia;
Host 170v, 4no.

Compare the amount of radiation, you will find that the radiation of the keyboard is the largest. At present, there are strict regulations on the radiation of electronic products in China. For example, the mandatory 3c certification is one of them. However, from the actual situation, it is not realistic to completely eliminate radiation in computer design. Therefore, as users, we can purchase tco-certified monitors, choose the chassis of major brand manufacturers or some special professional radiation protection products to avoid electromagnetic radiation problems. Although electromagnetic radiation is ubiquitous and ubiquitous, as long as we have sufficient knowledge of radiation and proper use of computers, we need not panic about the electromagnetic radiation of computers at all.

In fact, all the daily household equipment that uses electricity will produce electromagnetic radiation, whether it is harmful to the human body, the most important thing is to look at the amount of radiation energy. According to the regulations of the International Radiation Protection Association and the International Labor Organization, the safety intensity of the electromagnetic field is 0.2-0.4 microtrails (this is the safety limit of the electromagnetic field when exposed to a computer for 24 hours), and below this intensity is not harmful to the human body. Some specialized research institutions have tested the electromagnetic field strength of the computer, and found that the electromagnetic field strength close to the fluorescent screen is 0.9, but about 5 cm away from the screen, the intensity is less than 0.1, and a little further to 30 cm (this is the computer operator ’s The habitual distance between the body and the screen), its intensity can hardly be measured. In addition, electromagnetic waves in space are indeed ubiquitous, but under normal circumstances, the intensity of this electromagnetic radiation is very small and will not cause harm to human health. The “Regulations on Electromagnetic Radiation Protection” promulgated by our country stipulates the standard limits for equipment contaminated by electromagnetic radiation and the impact on personnel. Only when the electromagnetic wave reaches a certain intensity, the key protection is needed.
